System Requirements
A SmarTrunk II radio trunking system employs low cost radio
communications equipment and SmarTrunk II technology, which is
installed at both the base station and the subscriber radios.
The base station equipment required for each channel consists of a
SmarTrunk II controller connected to a standard VHF or UHF radio
repeater. For telephone interconnect applications, the controller is
also connected directly to a standard telephone line via a RJ-11 jack.
Each channel can support one individual conversation. Therefore, a
three channel system can support
three simultaneous private
conversations.
Since SmarTrunk II is an “overlay”
system, each of the subscriber
radios must have a customized
logic board to control the radio’s
operations. SmarTrunk Systems,
Inc. manufacturers customized
logic boards for over many
different radios. Please see the
“SmarTrunk II Logic Board
Collection” (Appendix A) which
lists all the mobile and portable
radio models that are compatible
with SmarTrunk II.
